Install Ubuntu 18.04.1 on external Thunderbolt 3 SSD connected to Dell XPS 15 9570

  • 772

I have a Dell XPS 15 9570 running Windows 10.

I purchased an external Dell Thunderbolt 3 drive to enable me to boot Ubuntu without touching the Windows 10 install on the internal SSD.

I have configured the BIOS to allow booting from Thunderbolt 3 using the instructions here:

https://www.dell.com/support/article/uk/en/ukdhs1/sln301218/how-to-boot-to-an-external-device-using-usb-type-c-connection?lang=en

I have a USB key with the Ubuntu 18.04.1 installer.

I successfully booted from the USB key.

I can see the Thunderbolt 3 drive from the installer and the installation appears to complete successfully.

When I reboot, I can see the Thunderbolt 3 drive in the boot sequence in the Bios Boot options.

When I attempt to boot from the the Thunderbolt 3 drive a message pops up too quickly for me to read and the machine restarts.

Anyone got any experience of a similar setup?

    I've just tried to boot Ubuntu 20.04 from the same Thunderbolt 3 disk and it works.

    The machine (Dell XPS 15 9570) is running BIOS version 1.15.0.
